Created attachment 477786 [details] Reproducible File Attempting to select text when RTL text is truncated results in a discrepancy between the actually selected range and the highlighted text range. During this issue, copying saves the actually selected range to the clipboard. Reproduction steps: 1) Open the HTML file(bug-report.html) attached to this ticket. 2) Resize the window to make the text ellipsis. 3) Select the text. The expected behavior is for the actually selected range and the highlighted text range to match, even when omitted.

It looks like selection painting, so going with Layout & Rendering component.
